This patch set adds very basic support for the interconnect framework to the Qualcomm portion of the UFS framework since the firmware on these platforms expects the interconnect votes to be present. The maximum throughput is requested to match what's already done in a few other drivers. Here's the relevant entries from the interconnect_summary file in debugfs that shows the two ICC paths are setup for the first UFS host controller on the SA8540p automotive board (sc8280xp). node tag avg peak -------------------------------------------------------------------- xm_ufs_mem 0 4294967295 1d84000.ufs 0 0 4294967295 qns_a1noc_snoc 0 4294967295 1d84000.ufs 0 0 4294967295 qnm_gemnoc_cnoc 115 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 0 40000 884000.serial 0 115 115 qhs_ufs_mem_cfg 0 4294967295 1d84000.ufs 0 0 4294967295 chm_apps 115 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 0 40000 884000.serial 0 115 115 qnm_snoc_sf 1000000 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 1000000 2500000 qns_gem_noc_cnoc 115 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 0 40000 884000.serial 0 115 115 qns_llcc 1000000 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 1000000 2500000 llcc_mc 1000000 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 1000000 2500000 ebi 1000000 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 1000000 2500000 qnm_aggre1_noc 0 4294967295 1d84000.ufs 0 0 4294967295 qns_gemnoc_sf 1000000 4294967295 1d84000.ufs 0 0 4294967295 a6f8800.usb 0 1000000 2500000 Brian Masney (2): scsi: ufs: ufs-qcom: add basic interconnect support arm64: dts: qcom: sc8280xp: add interconnect properties to ufs nodes arch/arm64/boot/dts/qcom/sc8280xp.dtsi | 8 ++++++++ drivers/ufs/host/ufs-qcom.c | 25 +++++++++++++++++++++++++ 2 files changed, 33 insertions(+) -- 2.38.1
